AM Ultimate Car Cover not waterproof anymore

[andrewdj]

I inherited it when I bought my DB11 Volante earlier this year and I'm going to assume it's 6 years old now. Anyway, when I take it off the car, there is water over much of the vehicle which clearly sits there.

Is there a way of re-waterproofing these that anyone knows of or should I resign myself to a new one? Car has to sit outside and my concern is mostly with keeping the roof in good condition rather than the car being rained on in general.

EDIT: looking at the online description for this cover, it states that rain will bead and run off. Well, it isn't doing that anymore just soaking in so I guess it needs re-waterproofing. I don't know if this will affect its breathability though, to prevent condensation forming under the cover, and at the least I would assume that the right stuff would need to be applied..

You sure its not condensation?

I have used Rainex in the past for motorcycle gear so it would probably work on a car cover.

There was a lot of water for it to be condensation but no, I suppose I'm not. The cover is supposed to be breathable as well to prevent that so my best guess is it's letting rain through.

I've never figured out how 'breathable' can also be waterproof.

Is it made of slightly stretchy grey fabric with an elasticated bottom? If so mine did the same.

Always had good results with Fabsil if it still exists.

Yes, with a soft red lining. Seems a bit pointless if it lets water in! It will be like technical outdoors clothing that can keep you warm and dry but let out moisture from perspiration. Did you keep yours?

Fabsil still exists. Would you just apply it to the cover or not bother with that and just keep the roof clean?

Mine didn't have the lining. It was fine for 2-3 years until the elastic lost its grip and water went through rather than off. I gave it to a friend who isn't as fussy as me!

Now I have a cheapo cover that's completely waterproof and fits equally well. It has elastic straps at each end because it can blow off in a gale (when you find it upside down on next door's drive and full of water and leaves it's really annoying!)

It’s a genuine AM cover designed specifically for my car. It fits snug and doesn’t blow around in the wind so I can be grateful for that.
